The Concrete Company Teaching Seawalls to Grow a Pulse
Ports and coastal cities already have to pour concrete. ECOncrete charges a premium to make that concrete useful to oysters, fish and engineers - then argues the habitat can pay for itself in permits, durability and avoided mitigation costs.
Impossible Metals
Impossible Metals is a San Jose-based ocean robotics company building autonomous underwater vehicles that harvest polymetallic nodules from the deep seabed one at a time. Its Eureka Collection System uses AI computer vision and a buoyancy engine to hover above the seafloor, pick up individual nodules containing nickel, cobalt, copper and manganese, and leave nodules with visible marine life untouched - an approach the company positions as a lower-impact alternative to both land mining and the seabed-dredging methods used by rivals.
